Abstract

To allow fuel economy, quietness, and drivability to coexist in a plurality of vehicle driving modes, and to improve drivability by preventing a kick-down amount from becoming excessive at a time of sudden opening of a throttle. In a system having a transmission control ECU (17) and an engine control ECU (42) as separate bodies, a transmission characteristic is selected by switching a transmission map (45) of the transmission control ECU (17) depending on a driving mode. The transmission map (45) outputs a target engine revolution number in order to control the transmission ratio of a continuously variable transmission (1). A motor driver (46) changes the transmission ratio by driving a motor (7) on the bases of the target engine revolution number and an actual revolution number. In response to the switching of the transmission map, a map is selected from each of a group of ignition timing maps (48) and a group of fuel injection time maps (49) in the engine control ECU (42). In another embodiment, a calculating unit 73 calculates a target engine revolution number based on a throttle opening degree TH and a vehicle speed V. A judging unit 78 judges whether a throttle opening degree variation ΔTH is larger than a ΔTH judgment value. If the variation ΔTH is larger than the ΔTH judgment value, a small value is added to a throttle opening degree TH for finding a target engine revolution number. If the variation ΔTH is smaller than the ΔTH judgment value, a large value is added to the throttle opening degree TH for finding the target engine revolution number. In the calculating unit 73, there is a previously prepared map where the target engine revolution number Netgt becomes larger as the throttle opening degree TH is larger.
